Harperbury Hospital, Radlett

Harperbury Hospital was a former mental health and learning disailbities hospital built on the remains of world war 1 hangers. A large part of the hospital was closed in 2001 and those bulidings have rapidly deteriated over the years. I visited most recently in 2013 but since then a new purpose built building has been established in the middle of the original site – leaving all the old buildings now closed and derelict.

The new building retains the newer name of ‘Kingsley Green’ and continues to offer a variety of services.

Sorry everyone, due to multiple arson attempts, all the buildings there have been boarded up, on site security and alarms have been beefed up massively. The only way in, is through the service tunnels. The hospital buildings are placed in a big ‘D’ Shape. – Follow the path round to the middle of the curve and you will find an open man hatch – Thats your way into all the buildings. The tunnels are long, dark and very asbestos-y. I dont know how you’d get out of the buildings you climb into though.

I tried to go here today, I needed some photos for a project. Wish I could of gone with someone who knows what they’re doing, we got caught by security! I think we went in the wrong way entirely, but I really want to go back and try again. Does anyone know the best way to get into the premises?

Luke, any updates on the situation? We went there last month (Still a newbie to the tunnels – would love to go back to explore them!) and could see visable signs of squatters in one of the buildings that “closed” in 2011 (if I’ve got my dates right)

If you don’t mind a bit of asbestos and aren’t claustrophobic, there’s some service tunnels running under the complex that nicely link up several of the buildings. We traveled from the first building with the car park out front all the way to the empty hall, bypassing security entirely.
